HgCdTe (MCT) Photovoltaic Detector

PEM-10.6-2×2-PEM-SMA-wZnSeAR-48

2.0 – 12.0 µm, ambient temperature, multiple junction

PEM-10.6-2×2-PEM-SMA-wZnSeAR-48 is uncooled IR photovoltaic multiple junction HgCdTe detector based on photelectromagnetic effect in the semiconductor – spatial separation of optically generated electrons and holes in the magnetic field. This device is designed for the maximum performance at λopt = 10.6 µm and especially useful as a large active area detector to detect CW and low frequency modulated radiation. This device is mounted in specialized package with incorporated magnetic circuit inside and SMA signal output connector. 3° wedged zinc selenide anti-reflection coated window prevents unwanted interference effects and protects against pollution.
